What is the 4 wheel drive button for on a 2004 Toyota 4 runner?

The 4-wheel drive button on a 2004 Toyota 4Runner engages the vehicle's four-wheel drive system, allowing power to be distributed to all four wheels for improved traction on slippery or uneven surfaces. This feature is especially useful in off-road conditions, such as snow, mud, or gravel. The button typically switches between 2WD and 4WD modes, providing drivers with the flexibility to adapt to changing road conditions. Always refer to the owner's manual for specific instructions on using the system safely.
